1. Product Description


A fume hood (sometimes called a fume cupboard or fume closet) is a type of local ventilation device that is designed to limit exposure to hazardous or toxic fumes, vapors or dusts.

A fume hood is typically a large piece of equipment enclosing five sides of a work area, the bottom of which is most commonly located at a standing work height.

Two main types exist, ducted and recirculating (ductless). The principle is the same for both types: air is drawn in from the front (open) side of the cabinet, and either expelled outside the building or made safe through filtration and fed back into the room. This is used to:

-protect the user from inhaling toxic gases (fume hoods, biosafety cabinets, glove boxes)
-protect the product or experiment (biosafety cabinets, glove boxes)
-protect the environment (recirculating fume hoods, certain biosafety cabinets, and any other type when fitted with appropriate filters in the exhaust airstream)

Secondary functions of these devices may include explosion protection, spill containment, and other functions necessary to the work being done within the device.

3. More About the Fume Hood


Choosing The Right Liner Material For A Fume Hood

A major consideration for fume hoods is the material of construction, specifically the liner material. There are many liner types that are used for various applications and the liner must be compatible with the chemicals being used. Selecting the right liner will make all the difference and play a major role in the longevity of your fume hood.

Epoxy Coated Steel

These liners are typically used in non-corrosive environments. If acids were to spill on this material, action must be taken as corrosion will occur. This liner is very economical and is heat-resistant.

Stainless Steel
When considering a steel option, fume hood liners typically come in Type 304 or Type 316 Stainless Steel. These types of liners are designed to provide greater life expectancy in harsh environments. The difference between the two is their makeup. Type 304 stainless steel contains 18% chromium and 8% nickel while Type 316 contains 16% chromium, 10% nickel, and 2% molybdenum. The molybdenum is added to help resist corrosion to chlorides.

Type 304 is the most versatile and widely used of the austenitic stainless steels. It is resistant to oxidation, corrosion, and durable. This material is very easy to clean and can come in a variety of finishes and appearances.

Type 316 contains 2% molybdenum giving it greater resistance to chemical corrosion than its Type 304 counterpart. It is durable, easy to fabricate, and clean. Being more resistant to sulfuric acid, chlorides, bromides, iodides, and fatty acids, this steel will also cost a bit more.

5. Fume Hood Maintenance


Hoods should be evaluated by the user before each use to ensure adequate face velocities and the absence of excessive turbulence.

• In case of exhaust system failure while using a hood, shut off all services and accessories and lower the sash completely. Leave the area immediately.

Fume hoods should be certified, at least annually, to ensure they are operating safely. Typical tests include face velocity measurements, smoke tests and tracer gas containment. Tracer gas containment tests are especially crucial, as studies have shown that face velocity is not a good predictor of fume hood leakage.

• Laboratory fume hoods are one of the most important used and abused hazard control devices. We should understand that the combined use of safety glasses, protective gloves, laboratory smocks, good safety practices, and laboratory fume hoods are very important elements in protecting us from a potentially hazardous exposure.

Laboratory fume hoods only protect users when they are used properly and are working correctly. A fume hood is designed to protect the user and room occupants from exposure to vapors, aerosols, toxic materials, odorous, and other harmful substances. A secondary purpose is to serve as a protective shield when working with potentially explosive or highly reactive materials. This is accomplished by lowering the hood sash.
